Virgin Media has announced that WiFi on London Underground will remain free for everyone throughout 2012.

WiFi from Virgin Media is already available in 72 London Underground stations, from the ticket halls to the platforms, with more stations due to be brought online by the end of the year.

The company says over 661,000 people are now online underground, with Waterloo, Victoria, King’s Cross, and Oxford Circus some of the busiest connected Tube stations.

No stations in Hammersmith and Fulham have yet been activated, but Earls Court, Hammersmith and Shepherd's Bush Central Line Station are all scheduled to be activated soon.

Jon James, executive director of broadband at Virgin Media, says: "WiFi on London Underground has been an incredible success with hundreds of thousands of people kept up to date and entertained whilst travelling around our capital city.

" Commuters and visitors will be able to make use of the internet throughout 2012 and we’re in positive talks with potential wholesale partners to ensure a fantastic experience for all Tube passengers throughout 2012 and beyond."

Gareth Powell, London Underground’s Director of Strategy and Service Development, says: " WiFi at Tube stations is proving to be a very popular service. There are already 72 London Underground stations online and our engineers are working in partnership with Virgin Media to continue the roll-out in 2012."

Virgin Media says the comprehensive WiFi portal with TfL travel information, updates and London news and entertainment will remain free for all Tube passengers throughout 2012 and beyond.
